Title: Improvements in or relating to electrolytic capacitors and to electrodes for use therein
IPC: C25D11/12
Filed: 1961-07-04
Abstract: A duplex oxide dielectric coating is formed on an aluminium electrode by first electrolytically depositing, in a molten salt bath, an adherent film of porous substantially non-hydratable alpha alumina, and thereafter treating the film coated electrode in a "barrier" type electrolyte so as to form a dense non-porous film of gamma alumina in the interstices of the porous film.  The alpha alumina film is produced by using molten salt containing sulphate anions e.g. potassium bisulphate, ammonium bisulphate or mixtures thereof with sodium bisulphate having a melting point within the range 145  DEG C. to 245  DEG C.  The subsequent barrier type electrolytic treatment is effected within the temperature range 15  DEG C-50  DEG C. in a conventional electrolyte of e.g. ammonium borate, boric or tartaric acid or ammonium borate dissolved in ethylene glycol.

Abstract: 1,211,382. Removing impurities from a continuous web. D. WALKER. 12 Nov., 1968 [24 Nov., 1967], No. 24115/67. Heading D1N. Impurities such as burrs, seed and shive, and double cuts created in shearing are removed from a continuous web of textile fibres in which the fibres have already been made parallel by feeding the material web M continuously through a dabbing zone, defined between two spaced apart nipping positions A- and B, wherein the impurites are pushed to one surface of the web by reciprocating, closely spaced pins 4, the material then being fed to a stripping zone where the impurities are removed from the surface. The removal is preferably carried out by passing the material around a small diameter support roller 6 with the impurity-carrying surface outermost and removing the impurities by a fluted rotary beater 9. A second small diameter support roller 11 may be provided together with a pinned roller 14, rollers 7, 8 and 12 pressing the material against these support rollers. A second dabbing zone may be provided, defined by rollers B and C. Rollers B cause the material to leave the first zone at a faster speed than that at which it enters, and similarly rollers C cause the material to leave the second zone at an even faster speed. A clearer device consisting of stationary horizontal parallel wires 5 co-operates with the pins 4. Suction may be applied to the impurity carrying surface in the dabbing zones.

Title: Ballast unit for gas discharge lamps

Abstract: 1397265 Supply circuits for discharge lamps E VOGELI 24 May 1972 [24 May 1971 16 May 1972] 24324/72 Heading H2H A ballast circuit for a discharge lamp 6 having pre-heatable electrodes 5, 7 comprises a semi-conductor switch 31 connectible in parallel with the lamp electrodes and a control circuit which triggers the switch during successive or alternate half cycles of an A.C. supply to enable heating of the lamp electrodes, the conduction period of the switch being gradually reduced during successive or alternate half cycles until the lamp fires. When the system is initially switched on, a high charging current for a capacitor 32 flows through a resistor 42, the voltage across which breaks down a diac 43 to trigger the triac 31 early in the half cycle of the supply voltage. The voltage induced in a choke 3a, 3b is insufficient to start the lamp but heating current flows through the electrodes 5, 7 via the triac. A rectifier circuit 34-37 prevents the capacitor discharging so that the capacitor is charged to a higher voltage, during successive half cycles thereby gradually increasing the time taken for the voltage across the resistor 42 to reach the breakdown voltage of the diac. The firing of the triac is therefore retarded in successive half cycles until the voltage induced in the choke is sufficient to start the lamp. Once the lamp has ignited the reduction in the voltage across the electrodes ensures that the voltage across the resistor 42 is insufficient to trigger the diac. The effects of higher frqeuency harmonics of the mains supply are eliminated by an RC circuit 38-41, the capacitors of which have low reactances at these frequencies. Modifications are described in which the triac is replaced by a thyristor and a circuit in which the electrodes of series connected lamps are supplied via saturable chokes is also described.
